7/16-20 Right Hand Thread Jam Nut For Heim Joints Or Rod Ends

A jam nut is a low profile type of nut, typically half as tall as a standard nut. It is commonly used as a type of lock nut, where it is "jammed" up against another nut, tie rod, bung, or arm to lock the heim joint, rod end, or bolt in place. It is also used in situations where a standard nut would not fit.
